Earlier this year, Telstra released the Digital Inclusion Index along with its report on measuring Australia’s digital divide.

Last week in Sydney the company hosted a half day conference to look at the ramifications of the 2016 report.

Overall the report was good news with most indicators showing improvements although the gap between the connected and the most disadvantaged has widened since the first index was compiled in 2014.

In general, wealthier, younger, more educated, and urban Australians enjoy much greater inclusion. All over the country, digital inclusion rates are clearly influenced by differences in income, educational attainment, and the geography of socioeconomic disadvantage. And over time, some Australian communities are falling further behind.

The one factor the survey found that is declining nationally is affordability which the authors put down to Australians’ increasing reliance on the internet.

The Affordability measure is the only dimension to have registered a decline since 2014, but this outcome does not simply reflect rising costs. In fact, internet services are becoming comparatively less expensive – but at the same time, Australians are spending more on them.

That such a levy would be proposed by a government that was opposed to a National Broadband Network and to ‘Big New Taxes’ while in opposition is an irony left for Australian political historians to discuss but it shows how comprehensively the NBN project has failed.

Even sadder is the NBN isn’t delivering for businesses as it increasingly becomes apparent the network being built will struggle to deliver 21st Century services to most of the nation.

That businesses are struggling to connect emphasises just how serious the digital divide is becoming for the economy – as supply chains in every industry become increasingly globalised regions that aren’t connected risk being isolated from their markets.

Policy makers have to consider the costs of those communities and groups being isolated from the modern economy. If we are going to be serious about building a twenty-first century society then we have to consider how disadvantaged groups and regions access global networks as well as making sure they have the skills to benefit from these technologies.

Mapping the areas of the disadvantage is a good first step but we have to look at how we address the segments of our society that are being left behind.
